Última Quantification of aluminium in soil of the Solimões Formation, Acre State, Brazil Rev. Bras. Ciênc. Solo Bernini,Thiago Andrade; Pereira,Marcos Gervasio; Anjos,Lúcia Helena Cunha dos; Perez,Daniel Vidal; Fontana,Ademir; Calderano,Sebastião Barreiros; Wadt,Paulo Guilherme Salvador. The variety of soils in the State of Acre is wide and their chemical profiles are still not fully understood. The nature of the material of origin of these soils is indicated by the high aluminium (Al) content, commonly associated with high calcium (Ca) and magnesium (Mg) contents. The study objective was to use different methods to quantify Al in soils from toposequences formed from material of a sedimentary nature originating from the Solimões Formation, in Acre, Brazil. Trenches were opened at three distinct points in the landscape: shoulder, backslope and footslope positions. Soil samples were collected for physical, chemical, mineralogical analyses. The Al content was quantified using different methods. High Al contents were found in most of these...

Ano: 2013 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-06832013000600015 Depth distribution of exchangeable aluminum in acid soils: A study from subtropical Brazil Agronomy Rabel, Diego Oliveira; Motta, Antonio Carlos Vargas; Barbosa, Julierme Zimmer; Melo, Vander Freitas; Prior, Stephen Arthur. Due to potential crop toxicity, high aluminum (Al) availability requires increased attention when preparing agricultural soils. However, research examining the relationship between depth distribution of Al and soil weathering has received little priority in Brazil, particularly regarding the number of soil profiles investigated. This study analyzed 38 acid soils selected from Soil Surveys in southern Brazil to identify and isolate the effects of organic and mineral components on depth distribution of exchangeable Al extracted with KCl (AlKCl). These soil profiles were divided into the following three groups based on AlKCl depth distribution: Group I – decrease with depth; Group II – little variation with depth; and Group III – increase with depth. High... Tipo: Info:eu-repo/semantics/article Palavras-chave: Soil Science; Agronomy Ki index; Organic matter; Smectite; Kaolinite; Al oxides; Lime requirement.
